Naruto's opening eternal eye

The regenerative nucleus consists of three parts, one is the shell.

The second is that it contains the physical part of its own chakra.

The third is the nutrient solution that preserves and supplies the physical nutrients therein.

The shell only needs to be strong enough to protect the flesh inside, but not just anything will do.

Because to use ninjutsu, there must be a meridian that allows the internal chakra to circulate.

This is why when ninjas use stand-in techniques, they replace themselves with wood or captive animals that are specially used to perform ninjutsu.

In the original work, the scorpions later used as shells were actually ordinary wood used to make puppets.

Mo Nan didn't plan to spend any more effort on this, so he could just use some of the puppet-making materials left in Xie's scroll.

The most troublesome step should be the special chemical solution that serves as the blood and nutrient solution.

This chemical solution is not only needed to maintain the activity inside the regeneration core, but is also its energy source.

Ordinary ninjas consume the food they eat to make chakra, and the regenerative core cannot eat, so the consumed chakra needs to be replenished by this.

The last step that Scorpion has not completed before is here, but it shouldn't be difficult for Mo Nan to complete this step.

Because the nutrient solution that maintains the activity of plants and provides them with energy is much easier to obtain than the nutrient solution that preserves human bodies.

Mo Nan happened to have done some research on botany in his previous life, so he recalled the books on soilless cultivation that he had read in his previous life.

For the next few days, Mo Nan stayed in the Konoha Library, checking the current world's research on plants.

After summarizing for a period of time, Mo Nan gained a greater understanding of the way plants in the ninja world survived, combined with the experience of previous lives.

Mo Nan then made some modifications to the formula of the nutrient solution left by the scorpion to preserve the vitality of the animal's flesh.

Adjust the ingredients in it to make it suitable for use on plants.

The materials needed for the nutrient solution are not complicated and can be bought everywhere, and there is nothing sensitive about it.

Even if someone saw it, they wouldn't doubt what Mo Nan was doing for buying a lot of fertilizer and other things related to planting.

Konoha's number one medical ninja, isn't it normal to grow some fresh medicinal materials by yourself?

Mo Nan quickly made the finished nutrient solution. He went to the death forest to take a branch from the tree clone, and soaked it in the finished nutrient solution.

After a period of observation, Mo Nan was disappointed to find that the branch died quickly.

Mo Nan was puzzled, there should be no problem with his nutrient solution, even if there were some deviations in the data, it would not have no effect at all, and this branch died too fast.

Suddenly, Mo Nan seemed to think of something and suddenly realized.

He ignored the difference between plants and animals, and humans have blood vessels.

The nutrient solution originally designed by the scorpion only needs to be injected directly into the blood vessels of the preserved part of the body.

The blood vessels of the tree are very small, so the soaking cannot penetrate at all, and you need part of the tree root to do it.

Thinking of this, Mo Nan hurriedly went back to the Death Forest to take another branch, and then dug a small piece of root into the ground with soil.

Mo Nan's tree clone has been growing for many years, its branches and leaves are luxuriant, and its root system is also very developed, digging up a little bit will not affect his survival at all.

Mo Nan had tried it before, and the cell regeneration technique also worked on plants.

Back home, Mo Nan used medical ninjutsu to speed up the grafting of the removed tree roots and branches, and soaked them in the nutrient solution again.

Sure enough, there was a change this time, and the branches did not dry up and die again.

Under the observation of Mo Nan's Sharingan, the little chakra contained in this branch did not show any attenuation.

This shows that Mo Nan's nutrient solution is initially feasible.

Afterwards, Mo Nan went through some simple adjustments, made a more efficient and effective nutrient solution, and was about to start making his own version of the regenerative nucleus.

Mo Nan has observed before that in his tree clone, the place where the chakra is most densely distributed is the heart of the tree.

This is not very scientific. For a tree, the heart of the tree is actually not that important. The tree relies on its bark to transmit nutrients.

Logically speaking, if the tree has chakra, it should also circulate in the bark.

But it may be that some wonderful changes occurred when Mo Nan used infinite reincarnation, making the center of the tree become the place where the energy flow of the entire tree is greatest.

Mo Nan dug a large piece of bark near the root of the tree, dug out a piece of the tree core and part of the root system, soaked it in the nutrient solution made before, and put the bark back.

It was determined that the heart and roots soaked in the nutrient solution were the same as the previous branches.

Neither the life signature nor the chakra has any decay, and Mo Nan has obtained all the materials for making the regeneration nucleus.

Now the most technical step is to engrave the spell on the shell.

This technique is very complex, in order to extract the internal chakra and release chakra lines, which is the key to controlling the puppet.

At the same time, it also includes techniques for the receptors of vision, touch, hearing, and smell.

This is not difficult for Mo Nan, who has Sharingan and is also very precise and stable as a medical ninja.

Soon Mo Nan completed the operation on the shell, and then put the processed tree heart into the shell and fixed it, and added nutrient solution to seal the shell.

The last thing Mo Nan has to do is to activate the spell on the shell, and make a seal according to Scorpion's memory.

As Mo Nan formed a series of complex seals, the spells on the regeneration nucleus gradually glowed.

With Mo Nan's last sigh, those complicated spells suddenly shone brightly, and then disappeared completely.

Only one wooden character is left at both ends of the cylindrical regenerated nucleus cross-section.

The moment the technique was completed, Mo Nan found that his senses had changed again.

The senses that were originally shared with the avatar of Pharmacist Dou now have a set of regenerative core senses.

The original tree clone was unable to think, had no vision, hearing, smell, touch, and could not move.

Mo Nan has no way to control his chakra, only the ability to perceive external things.

After a part of this tree clone is made into a regeneration core, it is still part of the tree clone and still has chakra interaction with Mo Nan.

And because of the techniques in it, this part has vision, hearing, smell and touch.

This is not over yet, under the control of Mo Nan, a large number of chakra lines protrude from the regeneration nucleus.

The chakra lines support the regeneration core like hands and feet, allowing the regeneration core to move at will.

Mo Nan's regeneration core is quite large, more than five times larger than Scorpion's.

Because there are not many places in the human body where a large amount of chakra is distributed, there is no need to make it so large.

The chakra in Mo Nan's tree avatar was not very strong, and only a part was taken out, so the bigger the better.

The chakra in this part that Mo Nan took out was probably equivalent to about 1/10 of the entire tree clone.

But there are very few chakras contained in it, I am afraid there is not even a standard ninja chakra.

If this regenerative core is put inside the puppet, it should not be a problem to maintain the basic movement of the puppet.

But if you want to fight, it is estimated that you will soon lose your motivation due to the lack of chakra.

But Mo Nan had already made preparations before. He had already made some changes to the scorpion's formula, and wrote the formula of the Yin seal on it.

In this way, the regeneration core can continuously create chakra and put it into the Yin seal when it is not moving.

Then during the battle, the seal is released and bursts out in one fell swoop, giving the puppet a strong fighting power.

The puppet that will use the regenerated core has already been prepared, and Mo Nan took out the puppet of the third generation of Kazekage from the scroll.

At this time, the three generations of Kazekage puppets are quite different from the previous image.

Mo Nan doesn't quite understand this scorpion's approach. He clearly has the ability to make human puppets exactly like they were in life, but he only makes himself so beautiful, and the other puppets are as ugly as monsters.

Xie himself and other human puppets are his proud works, so they should treat them equally and make them equally perfect.

At least Mo Nan thought so, so he changed the appearance of Fengying Puppet.
